INSTALLATION
5
The RS-232 or Ethernet service port is connected to an external PC during
installation, calibration and if service is required. Normally this port should not be in
use. Optionally a modem can be implemented, which enables long distance
communication with the instrument for service purposes.
The LCD continuously displays the gas concentration, laser beam transmission and
instrument status (warning and fault messages). In Section 5.4 an array of the
different fault messages is given.

1.5 Software
Software for the SERVOTOUGH LaserExact Monitor consists of 2 programs:
1. A program hidden to the user and integrated in the CPU electronics, running the
micro controller on the CPU card. The program performs all necessary
calculations and self-monitoring tasks.
2. A Windows-based program running on a standard PC connected through the
RS-232 connection. The program enables communication with the instrument
during installation, service and calibration.
The operator will need to use the PC-based program only during installation and
calibration and not during normal operation of the instrument. See Chapter 4 for more
details.
